Oral Transmission of Chagas Disease by Consumption of Açaí Palm Fruit, Brazil

In 2006, a total of 178 cases of acute Chagas disease were reported from the Amazonian state of Pará, Brazil. Eleven occurred in Barcarena and were confirmed by visualization of parasites on blood smears. Using cohort and case–control studies, we implicated oral transmission by consumption of açaí palm fruit

Surto de doença de Chagas aguda associada à transmissão oral

Seven individuals living in a town in the Southwest of Bahia developed sudden signs of cardiac and systemic impairment, with lethality of 28.6%. Serological tests were positive at least in one test in the five patients examined. Forty percent of the Triatoma sordida mynphs found inside or around Trypanosoma cruzi were found by blood culturig in there out five cases the homes of these cases were positive for Trypanosoma cruzi. Transmission probably occurred through consumption of water contaminated with triatomine feces. These findings emphasize the necessity to evaluation the importance of vectors like Triatoma sordida in maintaining the endemicity of this disease.Sete indivíduos que viviam em uma cidade do sudoeste da Bahia desenvolveram sinais súbitos de envolvimento cardíaco e sistêmico com letalidade de 28,6% Trypanosoma cruzi foi isolado por hemocultura em três de cinco casos examinados. Testes sorológicos foram positivos em mais de um teste nos cinco pacientes, que os realizaram. Qinquenta por cento dos Triatoma sordida encontrados na residência ou no peridomicilio dos casos estavam positivos para Trypanosoma cruzi. A transmissão provavelmente foi devido à ingestão de água contaminada por fezes de triatomíneos. Estes achados enfatizam a necessidade de se avaliar a importância de vetores como Triatoma sordida na manutenção da endemicidade da doença
